The test statistics which will be used here is standard deviation.
<h3>What is standard deviation?</h3>
The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.
A volatile stock has a high standard deviation, while the deviation of a stable blue-chip stock is usually rather low.
Thus, Option D is true, as standard deviation is the test statistics which will be used here.

believe the correct</span> answer is: evidence-based practice.
In the evidence-based practice (EBP), the conscientious use
of current best evidence in making decisions about patient care, the

programs that reduce recidivism.
Explanation:
Herbert Hoover was under the impression that the stock market crash of 1929 was a simple market correction, that it would go away if everybody just acted like everything was normal, and that markets simply do these things from time to time. Billboards circa 1930 with the blurb "Wasn't the depression terrible?" kind of summed up his tone-deaf approach to massive unemployment and runs on banks. He honestly believed that government intervention was not the answer.
By the time Roosevelt took office in 1933, he understood that no quick solutions were to be had. He did start a lot of public works projects, like the Works Projects Administration (which gave a lot of people short-term employment teaching, painting post office murals, and cleaning up public lands) and the Tennessee Valley Authority (which put a lot of broke farmers to work putting a utilities infrastructure in place in parts of the South, putting the pieces of a post-agricultural economy in place).
He also instituted several "bank holidays" to discourage panic-driven depositors from taking all their money out of their banks. Austerity became the new normal in America and stayed that way until the US entered World War II.
They avoid being detected because this would throw off the behavior patterns that exist naturally and they don't want their presence being known since this might throw it off.<span />
